JACOB H. REIGHARD AND C. L. KNECHT, OF BIRMINGHAM, PENNSYLVANIA.

ATTACHMENT FOR HINGED COVERS OF GLASS VESSELS.

Specification of Letters Patent No. 29,718, dated August 21, 1860.

To all lwhom it may concern:

Be it known that we, JACOB H. REIGHARD and C. LOUIS KNEGHT, residing at Birmingham, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in the Mode of Fastening Metallic Caps to Glass Mugs, &c.; and we do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the annexed drawing, forming part of this specification, in which- Figure l, is a perspective view of a mug with a metallic cover attached on an improved plan. Fig. 2 is a vertical section through the handle of a glass mug at the point where the metallic cap is attached thereto.

It is a usual thing to furnish certain articles made of glass Ware, such as lager beer mugs, cream pitchers &c, with a cap or covering of metal, which closes down on to the glass edge or mouth of the vessel, and which is hinged, so as to open and shut, and is attached to the glass by fastening the lower part of the hinge to the top of the handle of the vessel. The mode of securing the hinge of the cap to the glass handle, has been heretofore to cast the lower hinge piece around the glass handle by forming the mold or matrix in which the hinge is cast around the glass handle, and casting the lower hinge piece so as to form a strap or belt around the handle. The effect of this is, notwithstanding the greatest care is exercised, that the heat of the metal, cracks the glass, so that there is great loss in this mode of attaching the metallic coverings. By our improved method, however, all danger of breaking the glass is obviated, and the covers may be very easily and rapidly attached to the glass.

To enable others skilled in the art to make use of our improvement, we will proceed to describe the mode of carrying it into practice.

The drawings represent our improvement as applied to a lager beer mug. The mug a is made of glass, being pressed in a mold in the usual way. The handle as well as the body of the mug is pressed, which is effected in the manner well known in the art, by means of a mold dividing vertically through the handle. On top of the handle, near to the body of the mug, is a fiat surface to serve as a seat for the lower part b of the hinge of the cover c. In pressing the glass mug, a hole is made in the handle, which passes vertically through the handle, at or near the middle of the hinge seat. This hole (which is at el Fig. 2) is somewhat enlarged at the lower end, so as to prevent the hinge from pulling out. This hole in the handle is readily made by inserting a pin at the proper place in the mold in which the mug is pressed. The cap or cover c is made to suit the fancy and the size and shape of the article to which it is to be attached. At one point in its circumference is a hinge composed as usual of two pieces, one e attached to the cover c, and inserted into suitable spaces in the lowerl piece b, the two pieces being united by av hinge pin. The under side of the lower hinge piece b is made flat and smooth, so as to set on its seat on the top of the glass handle, and a metallic pin f of the size of the hole in the glass handle, projects downward from the lower hinge-piece b in the proper position. By this pin f the hinge is secured to the glass handle. The pin is passed through the hole in the handle, and being a little longer than the depth of the hole, it projects through. The pin which is made of soft white metal (as the cap and hinge are usually) is then touched at its projecting' point, wit-h a hot iron, which melts it, and causes the metal to run into the hole, which being slightlyenlarged at its bottom forms a head at the end of the pin, and prevents its being drawn out of its place. As the pin is melted only at its extremity, the heat is not suiiicient to crack the glass, and the operation of putting on the covers may be performed very rapidly.

As the caps or covers, and the lower hinge piece, with its pin, are usually cast in a mold, and the glass mug is also pressed in a mold, the parts are made so as to fit exactly, without any adjustment.

This mode of attaching covers to glass vessels, is applicable to cream pitchers and various other articles of glass which may be made in molds.

Having thus described our improvements, what we claim as our invention, and desire to secure by Letters Patent, is

Attaching caps or covers to mugs and other articles of glassware, by means of a l H. REIGHARD and C. LOUIS KNEOHT, have hole pressed through the glass handle, of the hereunto set our hands.
